Heard pop sound, then no power

For awhile now the monitor has been having problems when cold. It would come on all fuzzy, picture would black out, come back, do it several times and I would power off monitor, then back on and it cleared up after 45 seconds. Yesterday I heard a pop and it went off, no power. Couldn't get it to come back on.

hi the cause is screen back light not working properly. you need to remove the back cover of the monitor to access the internal part of the monitor. then look for the connector of the cold cathode fluorescent tube back light going to the power inverter board of the back light you will noticed a dry joints which cause a loose connection that is why you hear a sound that cause of spark. you need to re soldered the connector or replaced if totally burned.

You will need to either send this unit to a service center; or open it up yourself and resolder the video connections as well as the power input section on the Inverter Board. Most of these are cold soldered and they tend to break away with age and movement. I you have the tools you may also want to test (with and ESR Meter) the Capacitors. Use a Fluke DVO meter to test the Transistors and Rectifier. TCC

The problem with your lcd monitor is that the picture board of your lcd monitor is faulty that is why it power on for one second goes gray and finally black with only sound.

Since the power led button is on and it still give sound but no display, it means the picture board of your monitor is bad.

All you need to do is to take the lcd monitor to any local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix all alone in other to complicate issue.
